research The Art of Repair in Surgical Hair Restoration Part I
The best results in surgical hair restoration come from careful techniques, optimal use of limited hair supply, correct hair direction, saving hair for key areas, understanding scarring effects, and adjusting hair graft density.
research International Society of Hair Restoration Surgery
Various techniques and tools for hair restoration were presented in 1998, including a mathematical model for donor area, use of lasers in surgery, methods for controlling grafted hair direction, and ways to increase graft yield. Satisfaction rates were around 39%, and studies showed trauma and dehydration can damage hair follicles.

research Human Scalp Hair Follicles Are Both a Target and a Source of Prolactin, Which Serves as an Autocrine and/or Paracrine Promoter of Apoptosis-Driven Hair Follicle Regression
Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.
research Resting No More: Redefining Telogen, the Maintenance Stage of the Hair Growth Cycle
The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.
research A Role for p75 Neurotrophin Receptor in the Control of Apoptosis-Driven Hair Follicle Regression
The p75 neurotrophin receptor is important for hair follicle regression by controlling cell death.
